| 摘 要： | 采用体积成形有限元分析软件DEFORM对半轴套管的一次热挤压成形过程进行了模拟,分析了成形过程中金属的流动情况,得出了凹模开裂的原因为圆角结构过小导致应力开裂的结论,对凹模结构进行了优化,优化后的结构不仅能有效地避免凹模开裂,而且更利于坯料成形和减小挤压力.

| Abstract: | Bulking forming FEM software DEFORM is used to simulate the first step hot extrusion for half axles.The flow of metal during forming process was analyzed.Stress cracking caused by undersize round radius was the reason for female die cracking.Not only female die cracking can be effectively avoided,also convenience of the blank forming and reduction of extrusion pressure are achieved under optimized structural die. |

| Keywords: | half axles first step hot extrusion stress cracking structural optimization |
